RAIL- ANCHOR Application filed December 22, 1919. Serial No. 346,&78.

To all 'whom it mayconcern Be it known that I, WILLIAM M. MITCHELL, a citizen of the United States, residing at Louisville, in the county of Jet`- ferson and State of Kentucky, have invented certain new and useful Improvements in Ral-Anchors, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

The invention consists in the features of novelty hereinafter described, illustrated in the accompanying drawing and particularly pointed out in the claims at the end of this specification.

Figure l is a view showing in vertical section a railway rail mountedupon a cross tie and showing in end' elevation my improved rail anchor applied to the base of said rail. Fig. 2 is a view in horizontal section on lines 2-2 of Fig. '1. View in horizontal section through the web of the rail, the base of the rail and the stop thereon being shown in plan. Fig. 4 is a View in vertical section on' the line H of Fig. 3. F ig. 4 is a view on lines 4 1 of Fg. 2. Figs. 5 and 6 are views similar to Figs. l and 2 but showing a modified form of the invention. Fig. 7 is aview similar to 'Fig. 3 but showing a modification. Fig. 8

is a view in vertical section on the line 8-8 of Fig. 7.

A designates a railway rail and B de notes one of the cross ties on which the rail is mounted. My invention is shown as embodied in a one-piece rail anchor the general construction of which is set forth and claimed in an application filed by me of even date herewith. This anchor comprises a jaw formed of an upper member c and a lower member c', an abutment plate 0 and a plate c extending downwardly from the inner edge of the member e' of the'jaw and at right angles to the jaw member c' and the abutment member 0 Fig. 3 is a' Preferably, each of the stops a has exten- T sions at the ends thereof between which is formed a recess to receive. the end of a screw D that passes through a threaded hole formed in the upper member c of the anchor jaw. The screw D as shown is provided with a lock nut d to guard the screw against accidentally working loose. The head of the screw is preferably of polygonal shape to enable it to be easily turned by a wrench.

In applying my anchor to a railway rail, the jaw of the anchor is forced over the base flange of the rail until the anchor is in the position shown in Fig. 1, after which the screw D will be turned downwardly until its lower end passes behind the stop a* and enters the seat between the end extensions a of the stop, after which the locknut d will be turned down to guard the screw against working loose. When the anchor has thus been applied to the rail, the screw, coperating with the stop a will hold the 'anchor in place upon the base fiange of the rail and as the rail tends to creep, its gripping movement will be resisted by the engagement of the abutment portion of the anchor with the cross tie B. This will produce a slight rocking movement of the anchor, causing its jaws to firmly grip the base fla-nge of the rail with what is known as a shackle action and securely hold the rail against creeping, being aided in this by the engagement of the screw D with the sto a I f desired, the end of the u per member c of the anchor jaw nearest to t e tie D may an edge or edges that will more effectively grip the outer face of the base flange of the' rail when the anchor is rocked slightly under the tendency of the rail to creep.

In the form of the invention illustrated in F igs. 5 and 6 of the drawing, the upper member c of the anchor is provided with The base` flange a of *the rail A is formed two screwsiD that pass through threaded upon its upper surface with one or more stops or seats a'* that are preferably formed upon the upper surface of the base fange of the rail by welding thereon a small body of metal, which can readily be done by several of the familiar welding processes now holes formed in the upper member oftle anchor jaw adacent its ends, lock nuts d being employe( u 'on both of these screws. When the anchor s thus provided with two screws D the base flang e a of the rail will be provided with two stops a similar to 'the stops hereinbefore described. Instead of providing the upper surface of the base flange of the rail with stops a projecting upwardly therefrom, it is obvious that seats or depressions (one or more) may be formed in the base flange of the 'rail to receive the `'lower ends of the screw or screws D.

jaw members and arranged to engage the face of the rail fiange to hold the anchor v in position thcreon, and a depending abutment adapted to engage the side of thetie and coperate therewith to rock the anchor in a vertical plane and thereby force said jaw into gripping engagement with the upper and lower faces of the rail flange.

2. A rail anchor co'nprising a 'short jaw adapted to be slipped laterally over one of the base flanges of a rail and having a threaded' hole and a *set screw passing through said hole to enga e the rail flange; an abutment depending rom said jaw to engage the side of a cross tie, the end of the lower member of said 'aw extending no farther than the hearing ace of said abutment, the lower member of said jaw and gagement with one of the base flanges of a r rail between the cross ties of the track, said jaw being provided with a threaded hole therein and with a set screw passing through said hole, said jaw having a depending abutment arranged below the j aw to engage the side of a cross tie and to rock the anchor in a Vertical plane and thereby force said jaw into gripping engagement with the upper and lower faces of the rail flange.

4. The combination with a railway rail havin the upper face of its base flange provi ed with a seat to receive the end of a screw, of a rail anchor comprising a jaw adapted to be 'slipped laterally over said base flange, the upper portion of said jaw being provided with a hole and a set screw passing through said hole to engage said seat and the lower portion of said aw being provided with a depending abutment to engage the side of a cross tie to rock the anchor in a vertical plane and thereby force said jawinto gripping engagement with the rail flange. i
